Hard to believe this is Woody Allen and not Richard Curtis
It gets a pass from me but I think Woody was just having fun at how easy this type of story is to tell.
⚠It's a long story ⚠
I thought the same thing - the film is like an American's fantasy of life in England.
Ironically the English press were critical of the film for that reason, even though they fawn over Curtis' films when he has no excuse!
In the case of this movie, i can forgive a lot of it because it was originally supposed to be filmed (and set) in The Hamptons but was relocated to London because of funding. The story makes a lot more sense when you imagine it taking place there.
